Key Management Service (KMS)

Alibaba Cloud’s KMS handles the creation and management of encryption keys for your infrastructure. It serves as the central repository for generating, storing, and rotating keys, ensuring that data at rest and in transit remains secured through standardized cryptographic operations. This service abstracts the complexity of key lifecycle management, providing a dedicated interface for controlling access to sensitive information across various cloud resources.

The platform suits teams needing centralized key governance without upfront commitments, but it lacks a free tier entirely. You pay strictly on a pay-as-you-go basis, meaning every key operation incurs a cost from the first request. This model works well for scalable environments but requires careful monitoring of API call volumes, as there is no zero-cost entry point for testing or low-volume usage.
